coloradocyclist.com has vredestein fortezza's on sale right now for 30 dollars. i have a set of them and love them. they're the one of the grippiest tires i've ridden. i've commuted on them for well over a year and have held up super well. plus, you can pump those suckers up to 145 psi. they make a great track clincher. i also have some of the conti attack/force tires and love the way they feel too. very responsive, but spendy.
